Primljeno (Recieved): 2011-07-13 Prihvaćeno (Accepted): 2011-11-15 Original scientific paper This paper presents welding current influence on spreading of electromagnetic field in TIG welding process. The quality of welding is analyzed by „Fast Fourier Transformation“ (FFT) on recorded current. Electric and magnetic field are measured using an instrument „Macshek ESM – 100 3D Fieldmeter“ [1]. W...

Welds made with 304 austenitic stainless steel play an important role in high-pressure hydrogen storage systems. However, there are few investigations of the effect heat input on embrittlement (HE) tungsten inert gas (TIG) welded steel. In this study, HE TIG is investigated. It was found that increase welding input, ferrite content weld shows a tendency to first and then decrease. From perspect...

Abstract TIG welded marine grade AA5083-F/ER5356 and AA5083-F/ER5356+Sc joints were friction stir processed with a pin less FSP tool, to explore the impact of process parameters on mechanical metallurgical characteristics weldments enhance weld strength. The microstructure welds was observed using optical SEM subjected tests like toughness, tensile, microhardness fractography, evaluate strength...

Understanding the joining process in real time during welding can help improve quality, reliability, and manufacturing efficiency. For this purpose, a laser ultrasonic method that detect situ quality without contact would be useful. However, behaviors of propagation as well melting with increasing temperature remain unclear. Therefore, study aimed to experimentally investigate in-process behavi...

The present study presents a numerical prediction of residual stresses (RS) using the single-pass tungsten inert gas (TIG) welding process for stainless steel plates and two-pass TIG pipes. effect heat exchange between material environment was studied. work consists two parts: first one is based on determination existence numerically Cast3M software, which has been validated by literature resul...
